OK, call me a slow learner, or whatever else I deserve, but I have locked the keys in my Mark a few times now with various excuses. I have found that the keypad works for entry if I leave the keys on the seat or any place except the ignition. One day I was fiddling before getting out and left the keys in the ignition (off) got out, slammed the door and then at end of day realized
I left them inside. Thought all I had to do was use the keyless but no way, it would not even light up. Called the BCAA (AAA) to get in then took the key out and tried the keyless and it worked. So now I would never leave the car running with key in ignition and doors locked, I'd never get in.
